Abstract (English):
The article describes the use of single-factor analysis of variance to assess the effect of the composition of the soil mixture on the growth of flower seedlings of Catharanthus roseus (Catharanthus roseus "Rose"). Data on the growth of seedlings were collected at regular intervals throughout the growing season. Before the analysis, the uniformity of the variance and the normality of the distribution were evaluated. Post-hoc analysis was performed to determine the differences between the seedling groups. This research contributes to finding optimal conditions for plant growth and is of practical importance for agriculture, forestry and urban management. Especially in the face of climate change and when working in an aggressive urban environment.

Keywords:
